Everyone who believes that Jesus is the Christ is born of God. Everyone born of God overcomes the world. Who is it that overcomes the world? Only he who believes that Jesus is the Son of God. And this is the testimony: God has given us eternal life, and this life is in his Son. He who has the Son has life; he who does not have the Son of God does not have life. (1 John 5:1, 4-5, 11-12, NIV 1984).
My Musings – When we were kids, we used to play a game called connect the dots. Sometimes connecting the dots ended with the completion of some kind of illustration. Sometimes it was taking turns drawing lines between dots to eventually create squares with a series of dots. Whoever completed the fourth line to close a square earned a point. Whoever had the most points once all dots were connected won the game. The strategy was to make sure you did not give your opponent the chance to complete a square on his/her turn, hoping they would leave an opening for you to complete a square.
As adults, connecting the dots has a whole different meaning. It means you figure something out based on multiple pieces of evidence or data points (dots). None of which gives you the complete picture until they are all connected. When you connect the dots, you understand the connections and relationships.
In the above Scripture, John is connecting the the dots for us. If you believe Jesus is the Christ, you are born of God. If you are born of God, you overcome the world. Only those who believe Jesus is the Son of God can overcome the world. Thus, born of God means overcoming the world. Believing Jesus is the Christ means believing Jesus is the Son of God. God gives eternal life only to those who has the Son. Having the Son means believing that the Son is the Christ. Having eternal life means being born of God and overcoming the world. Many dots, all connected.
My Advice – Make the connection.
